Here's my project:
I want to relay my lawn after having new paths laid. The old lawn is about ten inches below the levelof the new path and I want the new lawn to be level with the path.
Do I need to remove the old grass?
Or can I put topsoil/sand over it and lay the new turf on top?
Can/shoul I put a base of sharp sand to bring the level up and then put (say) four inches of topsoil on top of the sand before laying the turf?
Any other helpful advice would be appreciated.
